Please wait...The V2 is our reversible check valve (RCV 75) that allows a single pump to perform the basic live well functions necessary to keep your catch alive, in a passive or automatic manner. By mounting the pump to the valve body, the operator only has to decide whether he wants his live well functioning or empty. When the first fish is caught, place the valve in the "AUTO" position and turn on the pump. When the boat is off plane the pump will recirculate and aerate the live well water and simultaneously blend in a portion of fresh lake water. Used live well water is expelled out the overflow as fresh water enters to prevent any ammonia build up.
